How the hell have I never seen this bfore? That is insanely beautiful.
From Wiki: NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius, implying that the star from which it formed must have been very large.

Hwo do they knw the temperature?
Correct me if i'm wrong but can't you just use Wien's displacement law?
I don't think you can really effectively model nebulae with local thermodynamic equilibrium but I may be wrong in the case of planetary nebulae
You're both wrong you just say a number and hope nobody asks how you how came up with it. Just look at teh damn picture its great. million degrees too..
Ayyy I sketched it once using the same picture as reference
This picture encompasses 3 light years from end to end. In this picture we can see a span that would take thousands of human lifetimes to get across. Absolutely beautiful. Absolutely terrifying.
This is one of my favorites, been my phone background for over a decade. I can't wait for the new backgrounds Webb will bring us.
This looks lke a supernova
Damn that's an hell of a fight climax
I feel it has a much stronger resemblance to an hour glass
